Hello! I realize this is a rather old post and the original poster has probably long since moved on, but I'm having the exact same trouble.
I'm trying to run DataEase 5.15 on a Vista 64-bit machine through DOSBox. As on our Win98 machines, when you initiate the program, it says "DataEase..." and blinks the cursor for a few seconds, but unlike the Win98 machines, it just keeps blinking the cursor endlessly instead of starting up the program.
Here's what I did to get to this point:
Z:\>SET BLASTER=A220 I7 D1 H5 T6 (this done by DOSBox automatically)
Z:\>mount c c:\
Mounting c:\ is NOT recommended. Please mount a (sub)directory next time.
Drive C is mounted as local directory c:\
Z:\>c:
C:\>cd dease
C:\DEASE>de16m
DataEase...
And here's what the console shows:
DOSBox version 0.73

CONFIG:Loading primary settings from config file C:\Users\(***)\AppData\Local\DOSBox\dosbox-0.73.conf
MIDI:Opened device:win32
And that's it. It just sits there and blinks at me.
Thanks in advance for any ideas!
